How AI Face Blur Works

Powered by TinyFaceDetector β€” a lightweight neural network optimised for real-time detection.

πŸ€–

Face Detection

The AI scans the image pixel-by-pixel using a neural network trained on millions of faces to locate each person.

🎯

Bounding Box

Each detected face receives a bounding box with a slight padding to ensure the full face region is captured.

🌫️

Gaussian Blur

A multi-pass box blur algorithm approximates Gaussian blur β€” adjustable from subtle to maximum anonymisation.

Face Blur – Automatically Anonymize Photos for Privacy

Protecting identity in photographs is a critical requirement for journalism, social media sharing, medical case studies, and compliance with privacy regulations like GDPR. Manually masking faces in photo editors is tedious and prone to error. This tool uses AI-based facial recognition to automatically detect all human faces in your image and applies a strong Gaussian blur to anonymize them instantly.

Because privacy is the core purpose of this tool, it is designed with a strict zero-upload architecture. The AI model (MediaPipe Face Detection) loads directly into your browser, and all detection and blurring happens locally on your device. Your sensitive photos are never sent to a cloud server, ensuring absolute privacy for your subjects.
